This would explain why neither gtk3 nor qt settings have an effect because LibreOffice
then uses the "gen" plugin which is basically LO doing the UI itself.

Does export SAL_USE_VCLPLUGIN=gtk3 (install libreoffice-gtk3...) change it? That would
use the "gtk3" plugin. (As done automatically when LO detects it runs under GNOME)
